IAG 950 EJ25 Closed Deck Case - 14mm H.S.M., Fire-Lock - For Subaru WRX, STI, LGT, FXT

This is the more serious closed deck EJ case for builds that need more clamping, more sealing, and a foundation that matches a higher-power setup.

• Case prep: Closed deck case built for the 950-level range
• Hardware: 14mm H.S.M. with fire-lock strategy
• Best fit: Good match for engines that will see more boost and harder use than the 750-level combo

Fitment: WRX, STI, Legacy GT, Forester XT EJ25 applications

Why you'd choose it: Choose this when the engine plan is clearly beyond a mild setup and you want the block prep to reflect that.
